CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority under 35 USC § 119(e) of U.S. Provisional Patent Application No. 62/779,055 filed December 13, 2018, the contents of which are incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

[0002] The present invention, in some embodiments thereof, relates to footwear, and more particularly, but not exclusively, to a footwear for training, developing and enhancing proprioceptive and kinesthetic skills and neuromuscular control.

BACKGROUND OF THE INVENTION

[0003] Proprioception refers to the ability to know where a body part is located in space and to recognize movements of body parts (such as fingers and toes, feet and hands, legs and arms). Kinesthesia is a related term, and refers to the sensation by which position, weight, muscle tension and movement are perceived. In some of the medical literature, proprioception refers to the conscious and unconscious appreciation of joint position, while kinesthesia refers to the sensation of joint velocity and acceleration. Proprioception is often used inter- changeably with kinesthesia, and herein as well, the terms will beused interchangeably .

[0004] U.S. Pat. No. 6,979,287 to Elbaz and Mor describes novel proprioceptive and kinesthetic exercise apparatus, which provides significant advantages over other prior art apparatus, such as tilt boards or shoes with a single protrusion. The apparatus includes two bulbous protrusions protruding from the underside of footwear, instead of the single ball of the prior art boards and shoes. One of the protuberances is positioned more posteriorly than the other protuberance. The extra protrusion may significantly increase the possibilities and enable walking and accelerate and improve the results of proprioceptive and kinesthetic treatment plans. [0005] The foregoing examples of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those of skill in the art upon a reading of the specification and a study of the figures.

The Protuberance

[0062] Reference is made to Figs. IB and 1C, which are plan view simplified illustrations of protuberance adjustment system for footwear in accordance with some embodiments of the invention. In some embodiments, the protuberances 104/500 depicted by Figs. IB and 1C are interchangeable within a protuberance adjustment system 700. In some embodiments, the protuberance 104/500 comprises a protuberance center 1. In some embodiments, the protuberance center 1 is marked on the protuberance. In some embodiments, the protuberance center 1 is the concentric vertex of the protuberance 104/500. In some embodiments, the protuberance center 1 comprises a concentric point of at least a portion of a circumference of the protuberance 104/500. In some embodiments, the protuberance 104/500 comprises a protuberance pivot 2. In some embodiments, the protuberance pivot 2 provides a rotation axis for the protuberance 104/500. In some embodiments, the protuberance pivot 2 provides a rotation axis perpendicular to one or more of a diameter of the protuberance 104/500 and the outsole 102.

[0063] In some embodiments, the pivot point 2 is configured such that the angle between the rotation axis and the outsole 102 is 0-180 degrees.

[0064] In some embodiments, the protuberance 104/500 comprises one or more pointers 112. In some embodiments, the one or more pointers 112 are marked coordinates along the circumference of the protuberance 104/500. In some embodiments, pointers 112 are paired and arranged along a perimeter of protuberance 104/500. In some embodiments, one or more alignment lines 3 are colinear with each pair of pointers 112. In some embodiments, pointers are paired and diametrically opposed. In some embodiments, the protuberance 104 comprises 4-6 pair of pointers 112.

[0065] In some embodiments, the alignment line 3 crosses the protuberance 104 diameter. In some embodiments, the alignment line 3 crosses the protuberance 104 diameter through the protuberance center 1. In some embodiments, the difference of the distances between each of the collinear pointers 112 of at least one pair of collinear pointers 112 and the protuberance pivot 2 is 0-10cm. In some embodiments, the difference of the distances between each of the collinear pointers 112 of at least one pair of collinear pointers 112 and the protuberance center 1 is 0-10cm.

[0066] In some embodiments, each pair of pointers 112 is marked on the protuberance 104. In some embodiments, there are 4-8 pairs of pointers 112. In some embodiments, the pointers 112 are used to align the protuberance 104 with the outsole map 200. In some embodiments, only one pointer 112 is used to align the outsole map 200. In some embodiments, only one pointer 112 is used to align the protuberance 104/105 with the outsole map 200. In some embodiments, the alignment of one pointer 112 with the outsole map 200 misaligns the remaining pointers 112 with the outsole map 200. In some embodiments, the pointers 112 are numbered.

[0067] In some embodiments, the pointers 112 are divided to a plurality of sets 112. For example, in some embodiments, such as depicted by Fig. IB, the protuberance 104 comprises two sets of pointers 114A and 114B, and the sets of pointers, 114A and 114B, are symmetrical across a diameter of the protuberance. In some embodiments, such as depicted by Fig. 1C, and as described in greater detail elsewhere herein, the protuberance 500 comprises four sets of pointers. In some embodiments, such as the exemplary embodiment depicted in Fig. IB, each alignment line 3 is collinear with two pointers 112 marked by the same mark for example, alignment line 3-0 of fig. IB shows an alignment line 3 having two pointers 112 each labeled No. 0. In another example, alignment line 3-4 shows an alignment line 3 having two pointers 112 each labeled No. 4. In some embodiments, as in the embodiment depicted by fig. IB, each one of the two pointers 112 of an alignment line 3 is in a different set of pointers 114A and 114B. In some embodiments, the alignment lines 3 are numbered at either or both pointers 112 of the alignment line 3.

[0068] In some embodiments, the protuberance 104/500 comprises midline pointer 6. In some embodiments, the protuberance 104 copmrises at least one midline pointer 6, for example, a first midline pointer 6A and a second midline pointer 6B. In some embodiments, the distance between the first midline pointer 6A and the protuberance pivot 2 is larger than the distance between the second midline pointer 6B and the protuberance pivot 2. In some embodiments, the first and second midline pointers 6A and 6B are collinear. In some embodiments, the virtual collinear line of the midline pointers 6 crosses the protuberance 104/500 diameter. In some embodiments, the virtual collinear line of the midline pointer 6 crosses the protuberance 104/500 diameter through the protuberance center 1. In some embodiments, the midline pointer 6 splits the protuberance 104/500 symmetrically.

[0069] In some embodiments, the pointers 112 are numbered starting with No. 0. In some embodiments, the midline pointer 6 is numbered. In some embodiments, such as depicted by Fig. IB, the midline pointers 6 comprise pointers 112 that are marked with the No. 5. In some embodiments, such as depicted by Fig. 1C, the midline pointers 6 comprise pointers 112 which are marked with the No. 5 A and 5B.

[0070] In some embodiments, such as depicted by Fig. IB, the protuberance comprises an anterior section 116 and a posterior section 118. In some embodiments, each portion comprises a set of alignment lines 3. In some embodiments, the anterior section 116 is marked. In some embodiments, the anterior section 116 is marked with the letter A 8. In some embodiments, the posterior section 118 is marked. In some embodiments, the posterior section 118 is marked with the letter P 7. In some embodiments, the collinear line of the midline pointer 6 comprises pointers 112 that separates between the anterior section 116 and the posterior section 118.

[0071] A potential advantage of the protuberance coordinate system 110 is in that it enables alignment of the protuberance 104/500 with the outsole 102. This alignment allows a user to control the position of the protuberance 104/500 in relation to the outsole 102.

[0072] A potential advantage of the protuberance coordinate system 110 comprising a posterior section 118 and an anterior section 116 is that the protuberance coordinate system is used to control the positioning of a protuberance 104 that is placed on an outsole 102, and therefore the protuberance 104 is independent of the outsole 102.

[0073] Reference is made to Fig. 1C, which is a plan view simplified illustrations of protuberance adjustment system for footwear in accordance with some embodiments of the invention. In some embodiments, the protuberance 500 comprises a plurality sets of pointers, such as, for example, the four sets 502, 504, 506, and 508, as depicted in Fig. 1C.

In some embodiments, shifting one pointer 112 from one anterior longitudinal line 9 to the next shifts the protuberance center 1 by 0.5-10mm along the anterior rail midline 10. For example, in the embodiment depicted by Fig. 8 the distance between two consecutive anterior longitudinal lines 9 is 5 mm.

Posterior Shift of the Anterior Protuberance

[00117] According to some embodiments of the protuberance adjustment system for footwear there is provided a method for a posterior shift of the anterior protuberance 108. In some embodiments, the method comprises starting at the anterior protuberance neutral position 29 as explained in further detailed elsewhere herein. In some embodiments, the method comprises rotating the anterior protuberance over the protuberance pivot 2 in the posterior direction. In some embodiments, the method comprises rotating the anterior protuberance over the protuberance pivot 2 in the posterior direction such that the protuberance center 1 shifts in the posterior direction.

[00118] Reference is made to Fig. 9, which is a plan view simplified illustration of a posterior shift of the anterior protuberance in accordance with some embodiments of the invention. In some embodiments, the alignment of one pointer 112, for example the pointer 112 labeled No. 1, with the (Ma) axis 12-0 of the anterior coordinate system positions the protuberance center 1 on the (Ma) axis 12-0 1 -5mm posteriorly with respect to the (Wa) axis 19-0. In some embodiments, the alignment of one pointer 112, for example the pointer 112 labeled No. 2, with the (Ma) axis 12-0 of the anterior coordinate system positions the protuberance center 1 1 -10mm posteriorly on the (Ma) axis 12-0 with respect to the (Wa) axis 19-0. In some embodiments, the alignment of each pointer 112 with a longitudinal line 9 positions the protuberance center 1 on a latitudinal line 19. For example, in the embodiment depicted by Fig 9, the rotation of the anterior protuberance aligns the pointer 112 labeled No. 2 with the anterior central line 11, which positions the protuberance center 1 at a latitudinal line 19-2. In some embodiments, the distance between two consecutive matrix latitudinal lines 19, e.g. 19-1 and 19-2, 1 -10mm. In some embodiments, such as depicted by Fig. 9, the distance between two consecutive matrix latitudinal lines 19 is 2mm.

[00119] In some embodiments, the positions of the protuberance center 1 on the (Ma) axis 12-0 are obtained by rotation of the anterior protuberance 108. In some embodiments, the positions of the protuberance center 1 on the (Ma) axis 12-0 are obtained by aligning at least one of the pointers 112 with the anterior longitudinal lines 9. In some embodiments, each of the pointers 112 corresponds to a specific distance of the protuberance center 1 from the (Wa) axis 19-0. In some embodiments, the distance of the protuberance center 1 from the (Wa) axis 19-0 increases with the increase of the number of the pointer 112. In some embodiments, the distance of the protuberance center 1 from the (Wa) axis 19-0 decreases with the increase of the number of the pointer 112. In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the protuberance 104 from one pointer 112 to the proceeding pointer 112 is 1-10 mm.

[00120] In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the anterior protuberance 108 from one pointer 112 to the proceeding pointer 112 is constant. In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the anterior protuberance 108 from one alignment line 3 to the proceeding alignment line 3 varies. In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the anterior protuberance 108 from one pointer 112 to the proceeding pointer 112 increases when the rotation in counter-clockwise direction such as depicted by arrow 950.

Anterior Shift of the Anterior Protuberance

[00121] According to some embodiments of the protuberance adjustment system for footwear there is provided a method for an anterior shift of the anterior protuberance 108.

In some embodiments, the method comprises rotating the anterior protuberance 108 over the protuberance pivot 2 in the anterior direction such that the protuberance center 1 shift in the anterior direction.

[00122] Reference is made to Fig. 10, which is a plan view simplified illustration of an anterior shift of the anterior protuberance in accordance with some embodiments of the invention. In some embodiments, the alignment of pointers 112, e.g., the pointer 112 labeled No. 1, with the (Ma) axis 12-0 of the anterior coordinate system, positions the protuberance center 1 on the (Ma) axis 12-0 1 -5mm anteriorly with respect to the (Wa) axis. In some embodiments, the alignment of one pointer 112, e.g., the pointer 112 labeled No. 2, with the (Ma) axis 12-0 of the anterior coordinate system, positions the protuberance center 1 1 -5mm anteriorly on the (Ma) axis 12-0 with respect to the (Wa) axis.

[00123] In some embodiments, the alignment of each proceeding pointer 112 with the (Ma) axis 12-0 positions the protuberance center 1 on the (Ma) axis 12-0 at least 1-5 mm anterior to the preceding pointer 112. For example, in the embodiment depicted by Fig 10, the rotation of the anterior protuberance aligns the pointer 112 labeled No. 2 with the anterior central line 11, which positions the protuberance center 1 on a latitudinal line 19-4. In some embodiments, the distance between two consecutive matrix latitudinal lines 19, e.g. 19-3 and 19-4, 1 -10mm. In some embodiments, such as depicted by Fig. 9, the distance between two consecutive matrix latitudinal lines 19 is 2mm.

[00124] In some embodiments, the positions of the protuberance center 1 on the (Ma) axis 12-0 are obtained by rotation of the anterior protuberance 108. In some embodiments, the positions of the protuberance center 1 on the (Ma) axis 12-0 are obtained by aligning the alignment lines 3 with the anterior longitudinal lines 9. In some embodiments, each alignment of a pointer 112 with an anterior longitudinal line 9 corresponds to a specific distance of the protuberance center 1 from the (Wa) axis 19-0. In some embodiments, the alignment of a pointer 112, for example, the pointer 112 labeled No. 3, with one anterior longitudinal line 9, distances the protuberance center 1 from the (Wa) axis 19-0. In some embodiments, the alignment of pointer 112, for example, the pointer 112 labeled No. 3, with one anterior longitudinal line 9, opposes the protuberance centric point 1 from the (Wa) axis 19-0. In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the protuberance from one pointer 112 to the proceeding pointer 112 is 1-10 mm.

[00125] In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the protuberance from one pointer 112 to the proceeding pointer 112 is constant. In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the protuberance from one pointer 112 to the proceeding pointer 112 varies. In some embodiments, the difference in distance of the protuberance center 1 from the (Wa) axis 19-0 created by rotating the protuberance from one pointer 112 to the pointer 112 increases when the rotation in counter clockwise direction such as depicted by arrow 950.

In some embodiments, the method comprises rotating the protuberance into a position where the second midline pointer 6B is in the medial-posterior quadrant 406. In some embodiments, the method comprises rotating the posterior protuberance to align the midline pointers 6 with the posterior coordinate system 20. In some embodiments, the method comprises rotating the posterior protuberance 106 to align the midline pointers 6 with at least one laterally shifting line 27. In some embodiments, the method comprises rotating the posterior protuberance 106 to align the midline pointers 6 with at least one of the hatch marks 28 of a laterally shifting line 27. In some embodiments, the transition of a midline pointer 6 from one laterally shifting line 27 to the next results in a 1-5 mm transverse shift of the protuberance center 1 in the direction of movement.

[00131] For example, in the embodiment depicted by Fig 13 A, the shift of the posterior protuberance aligns the first midline pointer 6A marked No. 5 with the posterior longitudinal line 21 marked LI and hatch mark 28 marked No. 0 (Zero), on the lateral-anterior quadrant 404, which positions the protuberance center 1 on a posterior longitudinal line 422-1. In another example, the embodiment depicted by Fig 13B shows that the shift of the posterior protuberance aligns the second midline pointer 6B marked No. 5 with the posterior longitudinal line 21 marked L4 and hatch mark 28 marked No. 0, on the medial -posterior quadrant 406, which positions the protuberance center 1 on a posterior longitudinal line 422- 2.

[00132] In some embodiments, one or more of the anterior outsole map and the posterior outsole map comprise longitudinal lines that are unmarked, or in other words, do not have one or more hatch marks along the length of the longitudinal line.

Medial Shift of the Posterior Protuberance

[00133] Reference is made to Fig. 14, which is a plan view simplified illustration of a medial shift of the posterior protuberance in accordance with some embodiments of the invention. According to some embodiments of the protuberance adjustment system for footwear there is provided a method for medial shifting of the posterior protuberance.

In some embodiments, transition of a midline pointer 6 moving from one medially shifting line 26 to the next results in a 1 -5 mm transverse shift of the protuberance center 1 in the direction of movement.

[00136] For example, in the embodiment depicted by Fig 14A, the shift of the posterior protuberance aligns the first midline pointer 6A marked No. 5 with the posterior longitudinal line 21 marked Ml and hatch mark 28 marked No. 0, on the medial-anterior quadrant 402, which positions the protuberance center 1 on a posterior longitudinal line 422-3. In another example, the embodiment depicted by Fig 14B shows that the shift of the posterior protuberance aligns the second midline pointer 6B marked No. 5 with the posterior longitudinal line 21 marked M4 and hatch mark 28 marked No. 0, on the medial -posterior quadrant 408, which positions the protuberance center 1 on a posterior longitudinal line 422- 4. Anterior/Posterior Shifts of the Posterior Protuberance

[00137] Reference is made to Fig. 15, which is a plan view simplified illustration of an anterior-posterior shift of the posterior protuberance in accordance with some embodiments of the invention. According to some embodiments of the protuberance adjustment system for footwear 100 there is provided a method for anterior and posterior shifting of the posterior protuberance 106.

In some embodiments, the method comprises aligning the midline pointers 6 with the hatch marks 28 of the ML center line 22. In some embodiments, shifting the midline pointer 6 from one hatch mark 28 to the proceeding hatch mark 28 creates a 1 -7 mm longitudinal shift of the protuberance center 1 in the selected direction.

[00138] For example, in the embodiment depicted by Fig. 15, the shift of the posterior protuberance aligns the first midline pointer 6A marked No. 5 with the ML central line 22 and hatch mark 28 marked No. -2, which positions the protuberance center 1 on a posterior latitudinal line 420- 1.

Combined Posterior/Anterior and Lateral/Medial Shifts of the Posterior

Protuberance

[00139] Reference is made to Fig. 16, which is a plan view simplified illustration of a combined shift of a posterior protuberance in accordance with some embodiments of the invention. According to some embodiments of the protuberance adjustment system for footwear 100 there is provided a method for a combined shift of the posterior protuberance 106. In some embodiments, a combined shift comprises of a posterior and a lateral shift. In some embodiments, a combined shift comprises of an anterior and a lateral shift. In some embodiments, a combined shift comprises of a posterior and a medial shift. In some embodiments, a combined shift comprises of an anterior and a medial shift.

[00140] In some embodiments, the method comprises starting with the posterior protuberance 106 in the neutral position, such as described in greater detail elsewhere herein. In some embodiments, the method comprises sliding the posterior protuberance 106 along the posterior rail 410. In some embodiments, the method comprises rotating the posterior protuberance 106 about the protuberance pivot 2. In some embodiments, the method comprises both sliding the posterior protuberance along the posterior rail and rotating the posterior protuberance about the protuberance pivot 2. In some embodiments, the method comprises aligning one of the pointers 112 with one of the markings of the posterior outsole map 400. In some embodiments, the method comprises aligning the midline pointer 6 pointer 112 with one of the markings of the posterior outsole map 400.

[00141] For example, in the embodiment depicted by Fig. 16, the shift of the posterior protuberance aligns the second midline pointer 6B marked No. 5 with the posterior longitudinal line 21 marked M3 and hatch mark 28 marked No. -2, on the lateral-posterior quadrant 408, which positions the protuberance center 1 on the intersection of a longitudinal line 23e and a posterior latitudinal line 420-2.

Protuberance Alignment

[00142] In some embodiments, an alignment of a specific pointer 112 with a specific coordinate point of the outsole map 200 is configured to place the protuberance center 1 in a predetermined position in respect to the outsole 102. In some embodiments, the predetermined position of the protuberance center 1 is located on the outsole 102.

[00143] In some embodiments, an alignment of a specific pointer 112 with a specific coordinate point of the outsole map 200 is determined by a position of the protuberance 104 along a rail. In some embodiments, the rail limits the range of movement of the protuberance pivot 2. In some embodiments, a specific pointer 112 is aligned with a specific coordinate point of the outsole map 200 by rotation of the protuberance 104 about the protuberance pivot 2.

[00144] In some embodiments, the position of the protuberance center 1 on the outsole 102 is determined by its distance from the protuberance pivot 2 and the size of the rail. For example, in some embodiments, the distance and the size of the rail are such that maintain the protuberance center 1 inside the outsole 102. [00145] In some embodiments, the distance between the protuberance center 1 and the protuberance pivot is L. Therefore, the rotation of the protuberance 104 about the protuberance pivot 2 allows aligning the protuberance concentric point 1 with any one of a set of coordinate points of the outsole map 200 that are at a distance L from the protuberance pivot 2. A potential advantage of this configuration is in that it provides an extensive range of alignment positions of the protuberance center 1 in respect to the outsole map 200.

[00146] In some embodiments, such as depicted in Fig. 7C, the midline pointers 6A and 6B are configured to align with different portions of the outsole map 200. For example, in some embodiments, the first midline pointer 6 A is configured to align with M3 to L3 and the second midline pointer 6B is configured to align with the lines M4, M5, L4 and L5 of the posterior outsole map 400.

Positioning Code

[00147] Reference is made to figs. 17A and 17B, which together are a table of position codes in accordance with some embodiments of the invention.

In some embodiments, the position code comprises of a set monovalent calibration positions for a posterior protuberance 106. In some embodiments, the position code comprises a set of monovalent calibration positions for the right and/or left foot. In some embodiments, the position code comprises positions of the protuberance 104 on the outsole map 200. In some embodiments, the position code corresponds between the position of the protuberance on the outsole and an orthopedic treatment.

[00148] In some embodiments, the position code defines the protuberance location. In some embodiments, the protuberance location code defines the location of at least one of the anterior left (AL), anterior right (AR), posterior left (PL), or posterior right (PR) protuberance. In some embodiments, the position code defines the protuberance diameter. In some embodiments, the protuberance diameter is or more of 85mm, 90mm, 95mm. In some embodiments, the position code defines the protuberance profile. In some embodiments, the protuberance profiles are labeled A, B, C, D. In some embodiments, the position code defines the protuberance hardness.

[00149] In some embodiments, the position code defines the protuberance center 1 position in relation to the anterior rail midline 10. In some embodiments, the position code defines the protuberance center 1 position in relation to at least one of the posterior rail midline 23 and the ML center line 22. In some embodiments, the position code defines which alignment line 3 pointer 112 is aligned with the outsole map 200. In some embodiments, the position code defines what part of the outsole map 200 the alignment line 3 pointer 112 is aligned with.

[00150] Fig. 17C, is a code line of position codes generated for a specific individual in accordance with some embodiments of the invention. In one implementation of the invention, a professional examines a subject and produces a position code configured to right a fault in a subject diagnosed by the professional. In some embodiments, a protuberance position code is generated automatically, for example, by a gait diagnosis system including, for example, a treadmill, an imager and a computer to improve performance of a healthy subject, for example, in sports. Reference is made to Fig. 18A-C, which are plan view simplified illustrations of a protuberance adjustment system in accordance with some embodiments of the invention.

[00151] In some embodiments the protuberance adjustment system comprises at least one lock and key system 1808. In some embodiments, the lock and key system 1808 couples the outsole 102 and the protuberance 104. In some embodiments, the outsole 102 comprises an outsole component 1802 of the lock and key system 1808. In some embodiments, the protuberance 104 comprises a protuberance component 1804 of the lock and key system 1808. In some embodiments, the outsole component 1802 and the protuberance component 1804 are the lock and key system 1808 of the protuberance adjustment system 700.

[00152] In some embodiments, the lock and key system 1808 comprises a socket and a corresponding plug, e.g., a socket 1802-8 and plug 1804-2 or, alternatively and optionally, a socket 1804-2 and plug 1802-8. In some embodiments, the lock and key system components are a pin and bore, e.g., pin 1804-2 and bore 1802-8 or, alternatively and optionally, pin 1802-8 and bore 1808-4.

[00153] In some embodiments, the protuberance component 1804 is positioned eccentrically on the protuberance 104. In some embodiments, the protuberance component 1804 is positioned concentrically with the protuberance 104. In some embodiments, a position of an outsole component 1802 is derived from a range of code lines, e.g., an averaged code line based on the range of code lines. Correspondingly, a position of a protuberance 104 lock and key component (e.g., lock and key component 1804-2) is derived from a range of code lines, e.g., an averaged code line based on the range of code lines.

[00154] In this embodiment, the code map is integrated into the predetermined position of the lock and key components 1802/1804 negating the need to mark the outsole map 200 and/or pointers 112 and/or alignment lines 3 on protuberance 104. A potential advantage of this configuration is in that a lock and key position is not patient specific and is suitable for several users or user types.

[00155] In some embodiments, the outsole component 1802 is positioned at a predetermined position of the outsole 102 in accordance with the code line and/or coding map 200. In some embodiments, the outsole 102 comprises a plurality of outsole components 1802. In some embodiments, the protuberance adjustment system comprises a plurality of protuberances 104 comprising distinct positions of the protuberance components 1804 in relation to the protuberance center 1 of the protuberance 104.

[00156] In some embodiments, the outsole components 1802 and the protuberance component 1804 are positioned to correspond to one or more positions in accordance with the position code (Fig. 17). In some embodiments, the outsole components 1802 and the protuberance component 1804 are positioned to correspond to a range of positions in accordance with the position code. For example, in some embodiments one outsole component 1802 corresponds with the range of positions of protuberance 104 in which one pointer 112 of the protuberance 104 is aligned in accordance with a plurality of consecutive coordinates based on a generated outsole map 200. In some embodiments, an outsole component 1802 coupled to a protuberance component 1804 corresponds with a range of positions based on the positioning code. [00157] In some embodiments, the protuberance 104/104-2/104-3 pointers 112 are invisible. In some embodiments, the outsole map 200 is invisible, or in other words, unmarked.

[00158] In some embodiments, the outsole 102 is universal and comprises a plurality of outsole components 1802 for positioning a protuberance 104 in a plurality of positions in accordance with the position code such that the outsole 102 is not patient specific. In some embodiments, the protuberance 104 is universal. In some embodiments, a universal protuberance 104 and a universal outsole 102 are coupled to produce a patient specific outsole adjustment system.

[00159] In some embodiments, protuberance pivot 2 is coupled to one of the anterior rail 204-2 and the posterior rail 410-2. In some embodiments, the anterior rail 204-2 and/or the posterior rail 410-2 is shaped to fix the protuberance 2 on the outsole 102. In some embodiments, the anterior rail 204-2 is placed on one of the points of the anterior outsole map 300 coordinate system. In some embodiments, the anterior rail 204-2 is centered at the anterior origin 17 of the anterior outsole map 300 coordinate system. In some embodiments, the posterior rail 410-2 is placed on one of the points of the posterior outsole map 400 and based on coordinate system. In some embodiments, the anterior rail 410-2 is centered at the posterior origin 25 based on the posterior outsole map 400.

[00160] For example, the embodiment depicted by Fig. 18A the outsole 102-2 comprises sockets 1802. In some embodiments, the outsole 102-2 comprises a plurality of outsole components 1802 sockets. In some embodiments, such as depicted by Fig. 18B-C, the protuberance 104 comprises a protuberance component 1804 plug configured to couple to one of the outsole components 1802 sockets.

[00161] In some embodiments, and in the embodiment depicted by Fig. 18A-C, coupling the protuberance component 1804-2 is with any one of outsole components 1802 provides six distinct positions of the protuberance 104-2 onto outsole 102-2. In some embodiments, coupling the protuberance component 1804-4 is with any one of outsole components 1802 provides six distinct positions of the protuberance 104-2 onto outsole 102-2. The combination coupling one of the protuberance components 1804-2/1804-4 with the outsole components 1802-2-1802-12 provides 24 distinct alignments of protuberances 104-2/104-3 on the outsole 102-2.
